The process design, simulation, and control of a solid oxide fuel cell (SOFC)/gas turbine (GT) hybrid power generation system combined with a compressed-fuel processing unit (CFPU) are presented. Given that CO2 is the input of the CFPU, the net CO2 emissions of this hybrid power system are suppressed under 324.2 g of CO2/kWh. Using the combined heat and power (CHP) approach, the hybrid power efficiency increases from 33% to 50%. Based on a single-input-single-output (SISO) control configuration, an inferential power control strategy using a static inferential model is implemented to improve the accuracy of the power estimation and effectively regulates the SOFC power output.
